2. 1. Components based on optical fibers with internal electrodes

   Author : Niklas Myrén; KTH; []
   Keywords : Poling; twinhole fiber; fiber electrodes; silver film electrodes; silver diffusion; quasi-phase matching; optical switching; frequency conversion; optical modulation;

   Abstract : The topic of this thesis is development ofdevices fortelecom applications based on poled optical fibers. The focusis on two different specific functions, wavelength conversionand optical switching.Optical switching is demonstrated in a poled optical fiberat telecom wavelengths (~1.55 mm). READ MORE

7. 5. Physiological demands of competitive elite cross-country skiing

   Author : Magnus Carlsson; Michail Tonkonogi; Christer Malm; Eva Andersson; Högskolan Dalarna; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Performance capability; maximal oxygen uptake; lactate threshold; lean mass; double poling; power output; maximal speed; sprint skiing; distance skiing.; Hälsa och välfärd; Health and Welfare;

   Abstract : Introduction Researchers have, for decades, contributed to an increased collective understanding of the physiological demands in cross-country skiing; however, almost all of these studies have used either non-elite subjects and/or performances that emulate cross-country skiing. To establish the physiological demands of cross-country skiing, it is important to relate the investigated physiological variables to the competitive performance of elite skiers. READ MORE
